At UCLA, we are working on a novel discourse based framework to model the coherence in video-captioning task. Text-level discourse structure aids in understanding a piece of text by linking it with other text units (such as surrounding clauses, sentences, etc) [1]}, [2]}, [3]}. Linguistic studies demonstrated that coherence of a text is reflected by its discourse structure and relations. In other words, coherent text favors certain types of discourse relation transitions.
